Description

Applicator and cartridge for such an applicator

Technical Field

The present invention relates to applicators for applying a product and light to an application surface, in particular the dermis or epidermis of the skin. The invention further relates to an envelope (capsule) for applying a product to at least a surface, in particular the epidermis of the skin.

Background

To dispense a product onto a surface, such as a substance onto the epidermis of the skin, it is known to use dispensers with applicator elements, such as balls that can roll over the surface. The substance is taken from a reservoir in the applicator by the ball and is transferred to the surface on which the ball rolls.

In addition, it is known to apply light to a surface, for example to optimise the effect of a substance applied to the surface.

From US 2008/262394 an applicator for distributing light to human skin is known, which applicator is a handpiece comprising a roller ball as a massaging element and a connector for connecting the handpiece to a light source in a control device. Light from the light source is transmitted to the handpiece through an optical connection such as an optical fiber and then radiated through the ball or along the side of the ball onto the surface to be illuminated. The ball is retained in a ball cavity of the handpiece. In one embodiment, the handpiece is provided with a plurality of openings around the ball, or gaps around the ball, through which cooling/heating air/liquid or massage oil/lubricant can be delivered to the skin during treatment of the skin. In US 2008/262394, such liquid to be dispensed is injected into the ball cavity in use from a source external to the handpiece through a conduit connected to the handpiece.

DE 3905517 discloses a hand-held device comprising a roller ball in a ball chamber, which roller ball is surrounded by a reservoir containing the fluid to be dispensed. The ball is able to pick up fluid when rolling and dispense the fluid to the skin. Light can be radiated onto and through the ball to heat the ball and perform phototherapy.

US 2011/0106067 discloses an applicator device for applying a substance to skin comprising a handle and a head. The head comprises a permanent part for connection to the handle and a disposable part comprising a base, a volume of the substance to be dispensed and a sponge for dispensing the substance. The sponge is hemispherical and is molded to the base, providing a volume between the base and the sponge for the substance to be dispensed. The outer hemispherical surface of the sponge provides an application surface and the sponge is perforated to allow the substance to be delivered through the perforations onto the skin of the user. The handle is arranged to generate a rotating magnetic force by rotating the first magnet by a motor or via induction of an electromagnetic field. A transmission is provided in a permanent part of the head to transmit power from the handle to the head. The second magnet is provided within an annular stator in the head. The second magnet is rotated by the rotating magnetic field and is used as an energy source in the head. The disposable part of the head is arranged to release a portion of the substance from the volume through the perforations of the sponge by means of a power transmitted by the permanent part of the head. In this device, the sponge will deform during the delivery of the product onto the skin and will absorb at least a part of the product. Furthermore, the sponge forms the boundary of the reservoir and thus the dispensing of the product will be at least partially controlled by the force applied to the sponge.

In an embodiment, the disposable component comprises a central opening. The permanent part of the head comprises a tubular extension provided with four LEDs at its free end. When the disposable part of the head is mounted on the permanent part, the tubular extension will fit in the central opening so that the LED extends outwardly from the hemispherical surface of the sponge.

US 2011/0040235 discloses a transdermal delivery device for a therapeutic agent comprising a mechanically vibrating element, a light source and heating and cooling elements fixed in a housing. One end of the housing forms a painting surface. In some embodiments, a reservoir containing a therapeutic agent may be included in the housing, well spaced from the application surface, and connected thereto by a series of narrow conduits. In one embodiment, the reservoir is provided as a replaceable bag with a solid closure for connection to the catheter. The piston is provided with a piston rod extending through the end of the housing opposite the application surface, which can be grasped by a user to push the piston against the bag to dispense the product. Alternatively, an embodiment is shown in which the reservoir is an integral part of the housing.

US 2009/0299236 discloses a device for therapeutic light treatment in which a ball is rolled across the skin surface during which light is radiated onto the skin.

US 2008/0014011 discloses a cosmetic and/or pharmaceutical dispensing device having a head. In an embodiment, a ball is provided in the head as the applicator element, and the light source emits light through the top of the head and/or through the ball. In embodiments, the entire device may be disposable, in other embodiments, a disposable cartridge containing a cosmetic or pharmaceutical composition may be mounted to the back of the head. A similar device is disclosed in US 2012/0207532, again disclosing that a disposable reservoir containing a large amount of product is mounted to the rear of a reusable head comprising a ball as an applicator element. The product is fed to the applicator element by natural flow (for example by gravity).

WO 2010/111997 discloses an applicator device for cosmetic and/or medical use having a ball as an applicator element. The device includes a disposable applicator component and a reusable base including a power source and a vibrating element. The substance to be dispensed is provided in a hemispherical reservoir extending around the ball. Furthermore, the compound is contained in the applicator part between the reservoir and the base, which needs to be mixed to provide heating or cooling to the substance. A light source may be provided in the base to radiate light through the compound, the reservoir with the substance and the ball to radiate the skin. This means that during use, the light will be affected by these elements and variations therein, such as the level and type of filler, the temperature of the mixed compound, the air gap between the compounds, etc., which will render the system inaccurate. Furthermore, in WO 2010/111997, the substance to be dispensed is clearly brought onto the ball due to the adhesion between the ball and the substance.

Detailed Description

The present invention is in no way limited to the embodiments specifically disclosed and discussed in this specification. Many alternative embodiments are considered to be disclosed or covered by the claims, including but not limited to combinations of embodiments disclosed herein or portions thereof, including but not limited to the embodiments and portions and features thereof shown in and discussed with reference to the figures.

In an embodiment, for example, more than one reservoir may be provided, opening into the space surrounding the movable element, so as to be able to dispense the ingredients or products that will only mix upon application, for example ingredients that do not provide a stable product over a long period of time or ingredients that provide a chemical or physical reaction upon mixing that is desired to occur on or near the surface 5. The reservoir for active dispensing can be designed differently, for example as a flexible bag, which can be compressed by a push rod or by, for example, squeezing. For this purpose, the pressure can be applied to the bag, for example, by air pressure or mechanically. Alternatively, the reservoir may have a membrane or other deformable wall instead of a piston, which may be deformed by a push rod or in a different manner in order to dispense the product. Instead of or in addition to the light source in the holder 15, the capsule may be provided with a light source. A plurality of movable elements may be provided in the enclosure, for example two or three such elements, such as balls or rollers. The device according to the present disclosure may be provided with an indicator system, such as an alarm, for example by light, vibration and/or sound, to indicate to the user that the applicator element should be moved to the next surface or the next portion of the surface in order to dispense the next quantity of product in the next step. In embodiments, the entire device may be disposable or reusable. However, it is preferred that the disposable capsule 17 be used with the reusable holder 15.

These and other variations are considered to have been disclosed herein.

In this description, embodiments of the applicator, the capsule and the dispensing method are disclosed by way of example only. In different embodiments, the same or similar parts and features have the same or similar reference numerals. Unless explicitly stated otherwise, the product to be dispensed in question may be used in all embodiments.

In this specification, words such as "substantially" or "about" should be understood to mean that the value or characteristic to which it refers does not necessarily correspond exactly. Small variations may be possible, such as, for example, 20% or less, e.g., less than 15%, such as, for example, 10% or less, or at least 5% or less of a given value.

In the present disclosure, an applicator, also referred to as device 1, will be understood to mean at least the following device comprising: a housing containing at least the light source and the energy source or a connector for the energy source; and an enclosure connected or connectable to the housing, the applicator element and the reservoir for the product to be dispensed. Preferably, the enclosure comprises the applicator element and the reservoir.

In the present disclosure, an enclosure may be understood to mean at least one component connected or connectable to said housing, which enclosure comprises at least a first coupling or connecting means or component for cooperation with a second coupling or connecting means or component provided in and/or on the housing.

The capsule according to the present description is preferably disposable, which may at least be understood to mean that the capsule contains a relatively small amount of product, in particular an amount of product for a single treatment process, is made of a relatively inexpensive material, and may be discarded after dispensing at least a substantial part of said small amount of product and/or after said single treatment process.

By using this disposable capsule, which can also be called a cartridge or a container (pod), different advantages are obtained. By using a new capsule in each process it can be ensured that the correct amount of product is dispensed in the process, or at least that a desired maximum amount is not exceeded. In addition, hygiene can be more easily ensured, since the same capsule and in particular the same applicator element are not used for different treatments, or are used by or for different users and/or surfaces. For example, it is possible to prevent the contamination picked up by the applicator element from being transferred to a reservoir of product to be dispensed in more than one treatment process. Moreover, the components that normally require optimal cleaning after use can now be discarded, thereby limiting the need for very careful cleaning. Furthermore, it will be easy to switch between products to be dispensed. Another advantage may be that the quality of the product contained in the reservoir of the capsule can be better guaranteed, in particular when the product may be susceptible to deterioration due to, for example, ageing or oxidation.

In the present description, the smaller amount of product contained in the reservoir may be, for example, less than 10ml, more particularly less than 5ml, more particularly less than 3ml, such as, for example, between 0.01ml and 1.5 ml.

In use, the product may be dispensed from the reservoir in a continuous or semi-continuous flow, for example activated by movement of the applicator element over the surface. The supply of fluid to the applicator elements may be effected, for example, by adhesive forces of the product with the moving applicator elements, gravity, capillary effects, or combinations thereof.

In other embodiments, in use, the product may be actively supplied to the applicator elements, for example, in a controlled flow and/or in a controlled, preferably predetermined, amount per time period. Active supply may be understood to mean at least applying a positive force to the product to supply a certain amount of product to the applicator elements. This may be achieved, for example, by a piston or a movable or deformable wall of the reservoir acting on the product under the influence of a displacement source or power source, such as, but not limited to, a motor or pump.

Preferably, the light source is provided in the housing. In embodiments, the light source may comprise or be formed by one or more LEDs. The light source may have different elements for different light frequencies. One or more light guides may be provided for guiding light from the light source through portions of the housing to the enclosure when properly mounted. The light guide may for example comprise one or more optical fibers or one or more light transmitting elements, such as for example elements made of transparent plastic or glass, such as but not limited to PMMA, Perspex (Perspex), PC, etc. The envelope may be provided with one or more windows or openings or be made of a light transmissive material to allow light from the light source to enter the envelope via the light guide and/or to enter and/or to pass through the applicator element and/or past the applicator element.

The disclosure relates in particular to an enclosure (which can be used as an applicator device) and a device for providing energy in the form of a light radiation wave. The device enables the simultaneous application of a product containing an active ingredient or forming a cosmetic product, and the application of light radiation having a selected wavelength onto or directly below the application surface, in particular the dermis of the skin.

More generally, the object of the invention can be:

a) capsules with various geometric configurations, which allow the application of a plurality of different products or with an optimal preservation capacity, or further with an optimal quantity, as required, and

b) the combined device allows:

at the same time, a product containing the active ingredient or forming the cosmetic is dispensed (or distributed and preferably applied, thereby placed) onto the living surface,

and emitting energy in the form of a light wave onto or below the surface via, for example, an electroluminescent diode (LED) from UV to infrared, thereby forming an interaction between the product and the energy.

It is also envisaged:

the capsule, particularly for skin treatment,

and a device to enhance the synergy between radiation and product activity in or on the epidermis.

It is to be understood that herein "product" is understood to mean a substance containing an active ingredient or forming a cosmetic product. Of interest here are products for topical (body part) application, which are cosmetics or pharmaceuticals with active ingredients. It has more or less fluid viscosity and composition, with viscosity and quality that may vary according to the desired benefit. Serum or liquid latex may be included, but if necessary, a somewhat thicker viscosity is not excluded. Preferably, the active ingredient has a biologically inducing effect.

Advantageously, the product contained in the envelope may be such that it reacts to a given wavelength and a given time of exposure to radiation.

The object of the present invention is a solution by means of which the substance to be applied is optimally protected to select the substance depending on the application in question, while always benefiting from light radiation (once applied) on the whole device, which is advantageous for the efficiency of the product.

In addition to the skin, the dispensing surface for the product may be the outer surface of a living organ, particularly an organ in need of treatment.

The proposed enclosure may be such that it provides a product dispensing area and comprises: a product supply in the body in communication with a dispensing area of the product; and first and second connection means for removable connection between the envelope and a housing in which the light source is arranged. The first and second connection means may be located at a distance from the light source.

Thereby, the interchangeability of the enclosure and thus the change of product is improved.

Another advantage is that, if desired, a single-use (single-dose) capsule is provided, and is therefore particularly hygienic, limiting the risks of bacterial proliferation and oxidation of the product (and in particular of the active ingredient). Furthermore, the same housing may receive various capsules, in particular capsules having different forms and/or contents.

To simplify the way in which the product or the body environment in which the product is placed is activated, it is recommended that the emitted light preferably passes through the mentioned product dispensing area.

For a given product, the amount of exposure to radiation (filtering of the light on the capsule) can be reduced by adjusting the focus while changing the optical index of the transparent part of the capsule, modifying the diameter of the rotational ellipsoid (which can be adjusted depending on the viscosity of the product) which can be used as an applicator element (see element 7 below) and/or modifying the product feed below the rotational ellipsoid (in particular, the ball) (again depending on, for example, the viscosity).

It is further proposed that the device comprises: a product applicator device for applying (placing) a product on said surface; and means for activating the emission of light by the light source, these activating means being able to be activated by the user at a distance from the dispensing area and/or by means of an intermediate portion of the applicator device, to allow the emission to be activated when the product is applied via said dispensing area, advantageously so that the light then passes through the applied product.

Furthermore, the safety of the user with respect to the emitted light can be checked.

In order to improve the uniform distribution of the product and the thickness of the product into the dermis or the surface of the innate porous organ, it is proposed that the capsule comprises a movable element having an outer wall, preferably convex, which contributes to or ensures the application of the product and/or is movable on said surface through the middle of the distribution zone of the product.

This is advantageous for the miniaturization of the device and for the interaction between the product application and the possible "massaging" effect which favours the product penetration into the porous surface.

In a preferred embodiment, the applicator element is provided in or on a sleeve having a relatively hard surface to contact the skin of a user to form or contain the product dispensing region. In the present disclosure, relatively hard is to be understood as being compared to the skin of a human body. Relatively hard is to be understood to mean at least, but not necessarily, not limited to being a sponge. Relatively hard may be understood to mean at least, but not necessarily limited to, having a surface hardness such that when the surface of the applicator element is pushed against the user's skin during application of the substance contained in the cartridge, the skin will be compressed more by the applicator element than by the skin. Preferably, the applicator elements are sufficiently stiff so that they are not compressed when the applicator applies a normal force to the skin to apply the substance during application.

In a preferred embodiment, the applicator element is provided in or on a relatively rigid sleeve for contact with the skin of a user to form or contain the product dispensing region. In the present disclosure, relatively rigid is to be understood as compared to the skin of a human body. Relative rigidity may be understood to mean at least, but not necessarily limited to, having the following configuration: i.e. when the surface of the applicator element is pushed against the user's skin during application of the substance contained in the cartridge, the skin will be elastically compressed by the applicator element without the applicator element being substantially deformed.

In a preferred embodiment, the applicator element is provided in or on a sleeve which is non-absorbing and impermeable to the substance contained in the sleeve, so that during application the substance will be distributed over at least a part of the surface of the applicator element, but substantially not penetrate into said surface.

To enhance the interaction between the transmitted light energy and the applied product, it is preferred that the light source emits light through the dispensing area towards the surface.

To provide proper product dispensing on an area of skin, an active product supply is preferably provided to ensure a constant flow of product to the applicator elements for dispensing.

To reduce oxidation and dehydration of the product contained in the apparatus, it is proposed that a protective foil or cover be provided on the movable element prior to first dispensing.

In order to optimise the application of the product and the passage of the light to the surface, it is proposed that the device provides an axis along which the light is emitted towards the surface, while the product supply is at least substantially transverse to or about said axis. In the first case, the light does not pass through the product, while in the second case this should be taken into account when determining the focus.

To further improve the application of the product without disturbing the passage of the emitted light, it is proposed to provide the product dispensing area with movable elements. Thereby, a synergistic product/light can be improved.

Still in respect of a good distribution of the product and this synergy, it is suggested that the displaceable element is pivotable about at least one pivot axis and has a convex outer wall, and/or that the displaceable element has an oval form, preferably a rotational ellipsoid, and is pivotable on the body and/or is rotatable in the body.

To protect the product without interfering with the removable connection between the capsule and the body of the device carrying the light source, or to facilitate the emission of light, the capsule may have a cavity open to one side towards the outside and may have a blind flange, preferably transparent to light, said first connection means of the capsule being located close to and transverse to the blind flange.

Thereby, at the same time, the separation and axial connection between the housing carrier and the envelope of the light source is ensured and simplified, without hindering the free passage of light/radiation.

With regard to the device itself, it is understood that the device is provided with the aforementioned (conditioned) distribution enclosure and a housing, which is therefore fixed in a removable manner to the housing by means of the first and second connection means, and in which a light source is provided, adapted to emit light or at least one wavelength towards the product distribution area, and therefore towards the distribution surface.

For the reasons already given, it is proposed that the light source emits light through the product application device, and preferably that the product application device comprises, as a movable element, an oval form through which the light rays can pass. Thereby, the above-mentioned synergy is improved and with the oval form, preferably a rotational ellipsoid, an optical system can be formed. The oval form of the housing may be arranged to accommodate the viscosity of the substance.

In an advantageous embodiment, for a simple and efficient optical system, the optical index of the movable element is constant over the entire movable element, which is a uniform solid or hollow body.

The movable element can be designed to be made of different materials, solid, hollow or liquid. Thus, in embodiments, the focal point may be adjusted to a certain depth in the surface, in particular the epidermis, in order to optimize the effect of the selected product. For the same purpose, the dimensions of the ovoid form and in particular its diameter and distance from the source allow to adjust the focal length and concentration of the light flow to a certain distance below the relevant application surface, in particular the dermis, if the light is to be emitted at least partially through the movable element.

Also with regard to the performance of the synergy between the application of the product and the effect provided by the radiation, it is recommended to limit the oxidation of the product while considering the device as a whole made up of two parts including a casing containing the light source and an envelope removably fixed to the casing and containing the product supply and the product dispensing area. Thereby, the capsule can be recharged/refilled, which allows the use of a disposable single dose product. The amount of product may then be a daily treatment dose.

The dose of product contained in the capsule can be particularly protected against oxidation by the packaging formed by the capsule, whereas it takes only a few seconds to remove the sealed protective film or cover before applying the product.

Alternatively, or in addition, preferably, a cover is provided in a removable manner for isolating the product supply from the environment, whereby a volume is covered under an atmosphere intended to protect the product from oxidation before the cover is opened for the first time.

For the transmission of light towards the surface and for protection, a first wall transparent to light may be provided, which is interposed between the light source and the product dispensing area and allows the light to pass through this area. The wall may be sized such that it is large enough to allow light to be concentrated onto or outside the area where the convex outer wall of the movable element contacts the body surface.

In this respect, for the efficiency of the synergy between the product applied and the light emitted towards the application surface, it is advantageous that the passage of the light in the optical system formed in the device concentrates it in the contact zone of the product dispensing zone with the surface to be treated, or slightly beyond it, deeper into the surface.

In this respect, a well-chosen solution is itself one in which the movable element with the dispensing area and/or the supply for it with the product defines an optical device for which the passage of light rays in the device concentrates these light rays in the contact area when the application means contacts the body surface. The movable element may be integrally formed to concentrate the light on said distribution area, which is the contact area with the body surface, or beyond a few millimeters, so that in case the distribution surface is skin, the focal point may be located in the dermis or between the dermis and the epidermis. In an embodiment, the light may be distributed over part or all of the contact area between the movable element, such as a ball, and the surface for application, such as skin. In an embodiment, the light may be distributed over an area surrounding a contact area between a movable element, such as a ball, and a surface for application, such as skin.

If a solution with a disposable envelope is considered, it is further suggested that the first wall, which is transparent to light, is fixed hermetically to or forms an integral part of the envelope with respect to the product. This enhances the protection against oxidation in particular.

A disposable capsule is understood to be a capsule that is to be replaced by another such capsule each time its product supply is depleted. Preferably, the disposable capsule is a capsule that cannot be practically refilled after use.

In the housing, the light source may be protected by a second wall transparent to light, which may be opposite to the first transparent wall in case the envelope and the housing are assembled. In principle, only air separates the opposing first and second walls.

To facilitate the use of the device at a plurality of said surface locations and the spreading of the product over the movable element, it is further suggested that the movable element is a rotational ellipsoid, in particular a sphere or a more oval form, pivoting in or on the device in all directions. Preferably, the element is a ball.

With regard to the use and ergonomics of the solution proposed to the user, it is suggested that the housing of the device provides a push handle for moving the movable element and a battery or power supply battery for the light source arranged in the push handle, the push handle extending in a direction towards the movable element. The housing may be designed as a push handle, meaning that the device can be held by the housing and moved over the skin by, for example, rolling a movable element such as a ball.

For safe use and taking into account that the light intensity of the light may damage the retina when the user is illuminated by the light, it is provided that, on the device, starting means are provided for emitting light by the light source, which starting means may comprise: a first body mounted with the application device and itself mounted so as to be translatable along an axis relative to a second body of the apparatus between a first position, in which the first and second bodies are axially spaced from each other while opening (interrupting) the electric circuit comprising the light source, in such a way that the light source cannot emit light, and a second position, in which the first and second bodies are axially close to each other while opening the electric circuit by pushing the movable element along the axis, so that the light source emits light; and biasing means provided between the first body and the second body for returning them to the first position in a natural manner. Thereby, the pressure on the movable element can activate the electrical contact and activate the device. The light will only be emitted if the movable element performs a pushing motion. In the rest of the cases, no light is emitted. This, preferably together with the presence of a light-tight protective cap movably mounted on the movable part forming the product applicator, allows both a proper protection of the product in the supply (via the cap) and safety of use, wherein light emission will only be present if the cap is removed and the movable element is pressed. In other cases, the activation device comprises an interrupter on/off and preferably a protective cover as described above.

With regard to the manner of product distribution and radiation emission on the surface, for the reasons described above, it is proposed that the method comprises applying the product on a product distribution area of the mentioned device, and emitting radiation towards this distribution area, preferably together with applying the product.

To improve the synergy between dispensing and radiation emission, while simplifying use, it is suggested that the product is provided in a product supply of the device, that the product is dispensed by rolling a movable element of the device and contacting the product in the product supply, and that a surface of an outer wall of the movable element is illuminated by a light source of the device through the movable element.

However, for certain products and certain applications, it is provided that the product can be easily placed in the path of the light emission, thereby altering the focus and improving the cellular response.

The bottom of the envelope is designed in a material transparent to the radiation, or alternatively can be filtered, which allows for the selection of a wavelength for a given envelope that is suitable for the conditions of use. For a specific product, for the same wavelength emission of the light source device, it is proposed to provide the light source emitting light in a housing of the device, to provide the product in a product supply comprising product application means and also a capsule associated with the device, whereby the capsule forms an optical system, to movably fix the capsule to the housing, and to modify the refractive index of the capsule optical system traversed by the light in dependence on the product, for example to change the frequency of the emitted light and/or to change the focus.

For reasons of ergonomics and ease of handling of the device, it is suggested that with the capsule fixed to the housing, the housing has a push handle for moving the movable element while advantageously extending in a direction towards the movable element and the light source, and wherein a power supply battery for the light source is arranged.

In order to check the interaction between the light energy generated and the dispensed product, and also as regards the safety of the user in terms of the emitted light, it is proposed to provide activation means which can be activated by the user at a distance from the dispensing area and/or by the intermediate portion of the movable element, thereby allowing to activate the emission of light rays by the light source when the product is dispensed via the mentioned dispensing area, so that the light flow passes through the dispensed product.

With regard to the dispensing of the product on the relevant surface and the formation of the heating and/or optical activation of the constituent cells of the living surface by the light radiation on the relevant surface, it is provided that the product is dispensed on the surface via a product application device and, preferably, simultaneously, the radiation from the light source is emitted towards the surface while changing the focus, thereby achieving an optical-biological modulation, the radiation preferably penetrating up to the fibroblasts responsible for the formation of collagen and blood vessels.

To reach the surface to be treated, the radiation from the light source can pass through the application device and in particular through the movable element. However, another configuration is conceivable: the light passes by the applicator element side, in particular around the applicator element, via a series of electroluminescent diodes, for example arranged in a circle.

Fig. 1 shows a dispensing device 1 for a product 3 of the type described on a surface 5 of a living body and shows the release of energy in the form of light rays to or illumination of the surface 5.

Product 3 contains active ingredients or forms a cosmetic product.

Preferably, the product has a liquid or cream viscosity.

The surface 5 may be the skin surface, or the (epidermal) dermis. Additionally, surfaces of human organs may be included, including internal organs accessible and treatable by surgery. More generally, it relates to skin painting, acne treatment, stretch marks, scar healing, such as but not limited to skin or internal organs.

The apparatus 1 has a zone 30 for dispensing the product onto the surface 5, the product being present in the zone 30 and this zone being contactable with the surface to be coated.

For dispensing the product and optimally activating the product, the apparatus 1 may comprise:

an applicator device 7 having a circular outer wall 70,

and a light source 9 consisting of or comprising an emitter of one or several rays 90 of light directed towards the surface 5, preferably by means of an element 7 having a convex outer wall 70.

Advantageously, the applicator element is movable in and/or on the body of the device.

Advantageously, the source 9 comprises one or several electroluminescent diodes. They may emit light according to different wavelengths, thereby allowing the effects on or in the surface 5 to be adjusted, preferably depending on the product 3.

Here, the product 3 is a liquid, and more precisely a fluid. Preferably, its viscosity allows the product to be distributed substantially uniformly over the entire dispensing area during the exposure time for the selected illumination/(light) wavelength.

The movable element is preferably a spheroid of a rotating oval, in particular a sphere, but preferably light can pass through the movable element.

Here, solid transparent glass spheres or solid polymer spheres may be included, or another product, solid or liquid may be included. Alternatively, the ball may be a hollow ball, for example a plastic ball.

In a preferred embodiment, the sphere allows wavelengths between 400nm and 1400nm to pass. Its diameter may be, for example, between 8-12mm, but it may be smaller or larger.

Filter colors may be added to the device, for example to a movable element such as a ball, for selectively avoiding transmission of certain wavelengths to the surface, for increasing the efficiency of a particular product, or for protecting a particular product.

The movable element is pivotally mounted about at least one pivot axis and, as can be seen in the drawings, the outer wall 70 preferably has a convex exterior.

However, for example a cylindrical or oval shape is possible, in which case the movable element 7 is itself pivotably mounted about a single axis of rotation perpendicular to the direction 13, it is proposed that the movable element 7 is oval, preferably a rotational ellipsoid, having an oval shape, such as a ball that is automatically pivotable in all directions in or on the device.

This improves a substantially even distribution of the product 3 or light over the surface 5, regardless of the spatial orientation of the device relative to the surface 5. Advantageously, the diameter of the ellipsoid of a rotational or ovoid shape, in particular a sphere, allows it to pass through all parts of the face.

The apparatus 1 further comprises a product supply 11 in communication with the dispensing area 30, here with the movable element 7.

In this respect, it is proposed that the product dispensing area 30 is located on the movable element 7, here in the figure on the surface of a convex (circular) outer wall 70.

To avoid light/product interference to a high degree, it is recommended that the product feed 11 be located transverse to the axis 13 parallel to the direction in which the light 90 is initially emitted towards the surface 5. But this is not essential: it is also possible to provide in the rear region, behind the applicator device 7 (see region 11a in fig. 2, or 11 in fig. 7 and subsequent figures). In fig. 12-15, other possible locations and schemes for the product supply are discussed. In this respect, it should be noted that the product supply may be understood as being formed by or comprising the reservoir 102 of the product 3.

To further improve the synergy between the product and the emitted light, it is proposed that the passage of the light or light rays 90 in the device concentrates the light in the area 25 where the convex outer wall 70 of the movable element 7 is in contact with the surface 5, or beyond by a few millimetres, as shown in fig. 6. Alternatively, the design may be such that the light is spread over a wider surface area, for example by refraction of the ball 7 and/or by other parts of the housing 15 and/or the envelope 17 or other parts of the housing 15 and/or the envelope 17, as shown for example in fig. 3.

Referring to fig. 6, the point 41 at which the energy is maximum is the position of the optical focal point defined by the refractive index of the optical system as a whole. The focus can be modified on the interchangeable capsule 17 (see further) to increase product efficiency by changing the refractive index of the optical path, i.e. by modifying the material, or by designing the parts in different materials.

Still referring to fig. 6, it is evident that the dispensing area 30 of the present product, here the outer surface of the movable applicator 7 applied on the epidermis 43 of the patient's skin, for which there is a massaging action, shows for example small protuberances 43', and increases the penetration depth of the product coating this surface into the dermis 45.

In particular, when the focal point 41 is in the dermis, the emitted light may be infrared light.

Alternatively, on the apparatus, the flexible

annular lips

19a, 19b can ensure airtightness in front of and behind the product feed 11, i.e. the reservoir 102, respectively, while allowing access to the front of the product film around the movable element 7 in the manner of a juicer only at 19 a. The clearance allowed by the lip 19a matches the product viscosity. The discharge and distribution of the product 3 on the surface of the movable element 7 can be performed by capillary action. The movable element may be mounted in the feeder space 11, i.e. in the housing 110, by a snap connection.

To simplify the design, it may be preferred that the product can pass between the movable element 7 and the bottom of the feed 11 (here the wall 21).

In addition, the device is provided with a housing 15, which housing 15 may form a push handle accommodating the light source 9, to which push handle the enclosure 17 comprising the product supply 11 and the movable element 7 is preferably movably fixed. This may simplify the use of the single-use capsule 17, which single-use capsule 17 then becomes disposable and may be discarded after use.

Here, the capsules can be interchanged or replaced, thus providing in particular several products to be applied, or diffusing several light rays, for example with different movable elements 7 at the same time. Diffusing several light rays is understood to include the possibility of changing the color of the light passing through the envelope due to differences in the refractive index, the coloration of the ball 7 or the shell, providing refractive elements such as, but not limited to, fresnel lenses or prisms or similar means for influencing the light.

In this way, the capsule 17 becomes replaceable, in particular disposable, refillable, so that the use of a single dose of product, such as different serum, is possible. The reservoir 102 of the capsule 17 may, for example, hold a small amount of product 3 to be dispensed, which may, for example, be less than 10ml, more particularly less than 5ml, more particularly less than 3ml, such as, for example, between 0.01ml and 1.5 ml. Obviously, other volumes are possible.

The supply 11, i.e. the reservoir 102, is provided in the body 110 of the capsule, the applicator element 7 being movable relative to the body 110.

A first wall 21 is placed between the light source 9 and the movable element 7, the first wall 21 being transparent to the light rays it allows to pass through and towards the movable element. In particular in fig. 1, the wall 21 is perpendicular to the axis 13, as shown for example in fig. 1.

It is recommended that this wall 21 is transparent to wavelengths between 400nm and 1400nm, preferably so that it does not substantially change the optical characteristics of the radiation and/or that its size and shape are large enough to concentrate the light on a focus defined according to the product and the desired effect (figure 6). Alternatively, the wall 21 may have an opening or window for allowing light to pass through.

Preferably, the light-transmissive wall 21 is fixed to the envelope 17 or is an integral part of the envelope 17, so that it is airtight for the product, thereby making the wall double-functional. The light source 9 will then be in an area isolated from the product contained in the supply 11, i.e. the reservoir 102.

To simplify assembly and disassembly and reduce the production costs of the two components, the shell 15 and the enclosure 17 can be snapped together by means of the lip 150 of the shell to resiliently retain the rear head 170 in the shell via the peripheral groove 103, the transparent wall 21 also engaging the rear head 170. The lip 150 and the groove 103 may form first and second connecting means or

elements

100, 101. This is advantageous in the case of assembly and disassembly using only the capsule 17. In fig. 1, 2, the connection means 150 of the capsule are indicated, in this example preferably formed by a peripheral groove 103 of the body 110, located close to the closing wall 21 and in the transverse direction of the wall 21 and therefore not obstructing the passage of light.

Further to this, and particularly shown in fig. 3, in the housing 15, the light source 9 may be protected by a second wall 210, the second wall 210 may or may not be transparent to the light of the light source 9 and being fixed inside this housing 15.

With the enclosure 17 and the housing 15 in the assembled state, the second wall 210 is opposite to the first wall 21.

Thereby, the light source 9 is placed between the first wall 21 and the second wall 210.

The two

walls

21, 210 may be parallel to each other. The light of a predetermined wavelength emitted by the light source 9 and emitted up to the application surface 5 travels successively through the first wall 21, the applicator device 7 and then through the layers of product 3 discharged onto the surface 30, each having its own refractive index.

Advantageously, the applicator device 7 defines an optical system. This may be hollow, with air inside, or any substance in solid, liquid or gaseous form, so that the focal point can be placed at any desired location at the exit of the enclosure.

For good retention and ease of handling after application of the product, it is proposed that the housing 15 comprises or forms a push handle or housing 151 for moving the movable element. Advantageously, the push handle extends in a direction 131 towards the movable element/applicator device 7.

In the housing 15, one or several power supply batteries of the light source 9 or a connector to the mains power supply is arranged in the push handle or housing 151.

Additionally, for use safety and long-lasting functionality, it is suggested that the movable element 7 is mounted to a first element 29 of the device 1 or engages this first element 29, while the first element 29 is in turn movably mounted for translation with respect to a second element 31 of the device following the axis. The axis may be an axis 13 passing through the source 9 and the movable element 7.

It is thereby ensured that the activation means 47, activated here and separated from the dispensing area 30 by the intermediate portion of the movable element 7, allow to activate the emission of light rays by the light source, while the product is applied through the dispensing area, so that the light flow passes through the applied product.

The fact is that the first element 29 carrying the movable element 7 is advantageously mounted for translation between a first position (fig. 4) and a second position (fig. 5):

in the first position, the first element 29 and the second element 31 are axially spaced from each other while the electrical circuit including the light source 9 is open, so that the light source 9 cannot emit light, an

In the second position, the first element 29 and the second element 31 are brought together axially by pressure of the movable element 7 on the surface 5 along the axis 13, while the circuit is switched on, so that the light source then preferably automatically emits the light rays 90.

Preferably, a biasing element 33 is provided between the first and

second elements

29, 31 to return them to the first position in a natural manner, as shown.

The first element 29 and the second element 31 are electrically conductive so as to form an interrupter 35, the interrupter 35 being open when the device 1 is deactivated (the circuit comprising the light source 9 does not emit any light) and closed if a pressure according to the axis 13 is exerted thereon (typically by contact with the application surface 5). The light can be emitted in the movable element 7 with a slight delay, which is controlled by an electronic decimal 39 (circuit delay, fig. 1), all for safety reasons.

Thereby preventing the light source from emitting intense light to the user's eye.

Alternatively, the first 100 and second 101 coupling means of the capsule 17 and the housing 15 are designed such that, once the capsule 17 is properly coupled to the housing 15, the

elements

29, 31 are brought into a conductive position, such as for example shown in fig. 5, and the circuit is broken only after removing the capsule 17 from the housing 15, as for example shown in fig. 4. This can have the advantage that the movable element 7, i.e. the ball, can also be moved slightly above the surface and still emit light.

Preferably, a cover 37, advantageously light-tight and therefore also radiation-proof, covers the product supply 11 and is removably fixed to the body of the apparatus, preferably to the enclosure 17. When mounted on the enclosure 17, the cover 17 may or may not rest on the movable element 7, which it covers here. Preferably, it is securely fixed to prevent (or at least limit) the passage of air towards the isolated internal volume 38 therebelow. In front of the first opening of the lid 37, the air pressure in the volume 38 may be lower than the outside 380 or be filled with an antioxidant substance to keep the product 3 free from oxidation or to limit oxidation.

It is particularly suitable to connect it to the single-dose capsule 17.

In order to adapt the device in particular to various types of application surfaces, such as skin, it is provided that the light source 9 generates different wavelengths alternatively or simultaneously during the continuous contact of the movable element 7 and the surface 5.

In this phase of discharging the product 3 onto the surface and of irradiating it by the light emitted by the light source 9, the intensity or sequence of the light beam produced can be modulated during the contact.

As already indicated, the reservoir or supply 11 may extend between the movable element 7 and the light source 9. This means that the refractive index of the product 3 should be taken into account. The product 3 to be distributed then forms part of an optical system, the refractive index of which is taken into account in the optical combination.

However, this is disadvantageous if the amount of product 3 stored in the apparatus, in particular in the enclosure, is reduced, the more the reduction, the more uneven the distribution of the product 3 risks. Furthermore, limiting the amount of products 3 in the radial periphery of feed 11 transversely to axis 13 can allow the omission of rear wall 21.

Advantageously, the dimensions of the movable element 7 are such that, for optimal application on the skin, it can travel over all the parts of the face, in particular also around the eyes. In a preferred embodiment, the movable element 7 applies the product itself obtained from the reservoir 11 by capillary action, by rotation due to friction on the dermis.

In fig. 7-11, the device 1 is shown, wherein the housing and the enclosure 17 can be separated in the axial direction (axis 13) by mechanical deformation of a hollow member 49 mounted in the housing 15. To this end, the

movable brackets

51a, 51b are carried laterally by the deformable portion 40 and are mounted pivotably or deformably with respect to the portion 40. The internal passageway 490 extends through the deformable member 49 along the axis 13. The internal passage provides

lateral bearing surfaces

53a, 53b parallel to the

pivot axes

510a, 510b, which are diametrically opposed with respect to each other, accessible to the user on the housing, perpendicular to the axis 13. By pressing these bearing surfaces, the hollow element 49 is thereby deformed transversely to the pressing direction and transversely to the axis 13, whereby the

brackets

51a, 51b are pivoted from a position naturally separated from one another to a closer position along the deformation direction, so that the capsule 17 can be fixed and/or removed relative to the housing.

In addition, as shown in particular in fig. 7, 8, the capsule 17 comprises connection means 52 forming first coupling means 100 for ensuring the desired removable fixation between the capsule and second connection means 54 forming second coupling means 101 of the casing 15, the first and second connection means being located at a distance from the passage area of the light rays coming from the light source 9 and passing to the product application area 70.

More specifically, the enclosure surrounds a cavity 53, the cavity 53:

open towards the outside on one side 530 (opposite to the movable element 7),

has a wall 21 which is separated from the supply 11 by the wall 21, and

comprising a side 55 surrounding the opening of the cavity 53, which side 55 belongs to the first connecting means 52 and the first coupling means 100, so that there is a removably received movable carriage 51, which carriage 51 belongs to the second connecting means 54 or the second coupling means 101.

To improve the engagement of the side portions 55, here annular, at the

ends

511a, 511b bent towards the inside of the

brackets

51a, 51b, the latter provide biasing ramps, wherein complementary ramps are provided at the inner periphery of the side portions (see fig. 11, the guiding of the ramps brings the brackets 52 close to each other).

In fig. 7, 9, 10, it can be seen that the activation means 47, 58 enable the emission of light by the light source 9 to be activated with the capsule 17 fixed in the casing, while it should be noted that the solution of fig. 1-5 advantageously comprises means 57, which means 57 comprise an on/off interrupter, which is always accessible to the user from outside the casing. The interrupter 57 is connected to the light emitter 9 to initiate light emission when the interrupter is closed.

In fig. 7, 9, 10, if the activation device 47 is now actuated by the pressure of the movable element 7 on the support via the surface 70 as previously described, the device 57 preferably also comprises an interrupter 63 on/off accessible from outside the housing 15.

With regard to the operation of the activation device 47, if this device 57 is in the "activated" position, it is provided to allow, with the capsule 17 fixed to the casing, the capsule to once again have the ability to move with respect to the casing 15 by displacement (translation) according to the axis 13, so as to:

c) in the first position (fig. 10), the circuit 59 comprising the light source 9 and the battery 27 is disconnected, an

d) In the second position (fig. 9), the circuit is closed so that the light source can thus emit light.

Furthermore, the mechanical action of the feet 61 connected to the ring 65 on the internal interrupter 63 can be selected, the ring 65 being held in the opening 64 of the housing, the

brackets

51a, 51b passing through the opening 64 in the direction of the enclosure.

Under the effect of the displacement of the capsule 17 according to the axis 13, generated by the pressure of the movable element 7, the ring 65 starts to press the internal interrupter 63 via the projecting feet 61.

As can be seen in fig. 9, preferably the outer side wall 550 of the enclosure (here the bottom of the side portion 55) presses on the ring 65.

For the fixing of the whole, the casing is furthermore provided with biasing means 67, such as a spring, which return the capsule to the first position in a natural manner, the interrupter being open (fig. 10, 11). Thereby, the pressure on the internal interrupter 63 generated by the axial pressure of the movable element 7 will counteract the stiffness of the biasing means 67.

The capsule 17 is thereby movable along the axis 13 relative to the housing.

Here, one of the guiding and axial stop means is provided through a

transverse bracket

51a, 51b positioned parallel to the axis 13.

A transverse bracket engaging in a groove perpendicular to axis 13 and formed between annular side 55 and inner shoulder 56, moves a short axial distance there. Preferably, there is also provided an annular outer stop means 58 for the housing/enclosure.

Regarding the aspects of the "impact" of the dispensing of the product 3 on the living body surface 5 and the transmission of light towards this surface, it should be noted that the aim is to achieve photo-biological regulation. What is involved here is stimulation by a column of photoelectrons (together with the emitted wavelength). For the skin, its penetration is recommended up to the level of cells of the dermis or hypodermis, the dermal matrix and in particular fibroblasts responsible for the formation of collagen and blood vessels (collagen is the main component of the skin, in particular responsible for the firmness and muscle elasticity of the skin). Stimulation of blood circulation provides an optimal supply of oxygen and nutrients to the cells for improving their function.

Preferably, the radiation of the source 9 towards the surface 5 comprises infrared, a source of heat.

As active substances, the following are provided in particular:

ACS III, molecular formula C37H69N05,

and (4) INIC: dipalmitoyl hydroxyproline

Type III collagen synthesis enhancer

Active ingredient for (human) skin care, which selectively enhances the synthesis of isotopically defined type III collagen,

"transporter" liposomes comprising dipalmitoyl hydroxyproline coated with hydroxyproline, which is used as a regulator in the phenotypic expression of fibroblasts.

Colatein (colatein)

Induction of HSP 47 accelerates extracellular transport of procollagen III as well as alpha chain folding of collagen during collagen synthesis and its externalization prior to extracellular fibril formation.

HSP 47, a chaperone protein dedicated to collagen synthesis.

In the case of therapeutic treatment or cosmetic indications of the product 3 and of the emission of the aforesaid light, as is clear from the foregoing, the conditions of use are preferably as follows:

the product is applied to the skin via a dispensing area 30 of the device, and

preferably, at the same time, light radiation is emitted towards the skin at the location of this distribution area, while using the focal point in order to produce a photobioregulation which penetrates up to the dermis, or up to the hypodermis, the cells of the dermal matrix and in particular the fibroblasts responsible for collagen and angiogenesis.

In the previous example, the product dispensing area is limited to the surface of the applicator element 7. As already mentioned, it can be provided, however, that the light energy emitted by the source 9, for example via a series of electroluminescent diodes, can pass laterally of the applicator element 7 and in particular around the applicator element 7 before reaching the surface 5. In this case, all or part of the light energy does not actually pass through the applicator element 7, and more generally also through the application means of the product. The important point is that the energy, here generated in the form of a light wave, reaches onto or into the surface 5 of the applied product 3.

It is clear that although the dispensing (and thus the distribution) of the product on the surface 5 is performed by the movable element 7, such an element may also be present if, as is preferred. The application of the product on the surface can be carried out in another way, for example by means of an associated dispenser independent of the device 1.

Thus, whatever the embodiment, the product containing the active ingredient or forming the cosmetic product is dispensed onto the surface 5 of the living body, preferably simultaneously with the application of the product, the product is activated by the transmission of at least one wavelength in the form of an energy line to the cells on or in the surface.

Fig. 12 schematically shows a perspective view of the device 1 for dispensing a product and light according to the invention as described in a sectional view along an intermediate section comprising the longitudinal axis 13. As shown in the other embodiments, the apparatus 1 comprises a housing 15 and an enclosure 17. The capsule 17 likewise comprises a ball 7 as an applicator element and rotatably mounted in the capsule body 110, so that the ball 7 can rotate freely in substantially all directions. The enclosure 17 comprises at least a first coupling or connecting means 100 for cooperating with a second coupling or connecting means 101 provided in the housing 15 and/or on the housing 15, as will be further discussed. By means of the first and second coupling or connecting

means

100, 101, the capsule 17 may be coupled to the housing 15 releasably. The first coupling or connecting means and the second coupling or connecting means may be as described with reference to fig. 1-11, or as discussed below.

In fig. 12, a cross-sectional view of the housing or shell 15 is shown, schematically illustrating a portion of the interior, including the active applicator unit 104 and the enclosure 17. As previously mentioned, other parts, such as a battery and circuitry for operating the device, are not shown for convenience. In fig. 13-15, a basic embodiment of an applicator unit 104 and an enclosure that can fit in a housing or shell 15 is shown.

Fig. 12A shows a cross-sectional view of a portion of the active applicator unit 104 and the enclosure 17, illustrating the general concept of active distribution and light guiding. In fig. 12A, the ball 7 is shown, the ball 7 being held by the housing 110 such that it can rotate in all directions. The portion of the ball 7 at the first side 105 of the housing 110 extends outside the housing 110 and may contact the surface of the product to be fed. On the opposite side, the housing 110 is provided with a cavity or reservoir 102 for the product 3. The reservoir 102 includes an outer peripheral wall 106, preferably generally cylindrical, defining an open end 107 opposite the ball 7. A wall 21 is provided between the ball 7 and the reservoir 102, the wall 21 having a relatively small opening 108 connecting the reservoir 102 with the space 11B surrounding the ball 7. A piston 109 is provided in the cavity or reservoir 102, sealing the peripheral wall 106 in a known manner, for example by means of O-rings or flexible sealing lips or the like, so that the piston 109 is movable along the axis 13 in the cavity or reservoir 102 towards the opening 108. Initially, the reservoir 102 will be filled with the product 3 to be dispensed, preferably substantially completely. The dimensions of the opening 108 may be chosen, for example, depending on the viscosity of the product, so that at atmospheric pressure, at least at room temperature, for example between 18 ℃ and 30 ℃ or even higher, the product will be contained in the reservoir 102, even if held upside down, i.e. with the opening 108 facing downwards.

When in this capsule 17, the piston 109 moves towards the opening 108, pressing the product, whose volume is approximately equal to the product of the frontal area of the piston and the displacement along the axis 13, through the opening 108 and against the ball 7, and is thus well-defined and controllable. If the ball 7 is pressed against the opening 108, the opening 108 may be better sealed to retain the product in the reservoir, e.g. before use of the capsule, whereas the ball can be pushed away from the opening 108 by the product when the piston is pushed towards the opening 108. The ball 7 may be pressed against the opening 108 by the cover 37, for example, before use.

In an embodiment, the ball 7 may be retained in the housing 110 without a seal closing a space between a portion of the ball surface and the housing 110. In an embodiment, the housing 110 may include a generally bowl-shaped retaining portion 110A having an upper edge 19 spaced from the ball surface by a small gap 115, as shown in fig. 12B and 12C. To this end, the rim 19 may be provided with a series of small spaced apart notches 19C or the like for defining the gap 115 while rotatably enclosing the ball in the housing 110. This may have the advantage that once the ball 7 picks up the product, the product is not wiped off by the seal. Thus, even a small amount of product dispensed at a time will be almost completely delivered to the surface 5 to be treated.

In the general embodiment of fig. 12A, the capsule 17 is pressed into the housing 15 along the axis 13 in the axial direction. In the housing 15, a push rod 111 is provided, driven by any suitable means (not shown in fig. 12A), such as but not limited to an electric, pneumatic, hydraulic or magnetic motor, a stepper motor, or by hand, for example by a screw knob outside the housing. The push rod 111 engages the side of the piston 17 facing the outside of the reservoir 102 through the open end 107, preferably fitting into a recess 112 of the piston to properly center the piston and push rod. One or more light guides 113 may be positioned around the wall 106 of the reservoir, extending between a position proximate to the light source 9 (shown here as a plurality of LEDs 9A) and a position proximate to or abutting the housing 110 of the enclosure 17. Thereby, light from the light source 9, in particular from the LEDs, may be transmitted through the light guide to the envelope 17, past the reservoir 102, unhindered by the product 3 in the reservoir 102, as indicated by arrow 90.

As can be seen in fig. 12A, the envelope 17 may be provided with a groove or cut-out 103, similar to the groove 103 shown for example in fig. 15, e.g. arranged at or below the transition between the portion 110A and the peripheral wall 106, in which groove the light guide 113 can be hooked, similar to the edge 150 in fig. 1 or the finger 52 in fig. 6-11, for holding the envelope 17 in place while providing a proper placement of the light guide near or adjacent to the end 116 of the housing 110 of the envelope 17. The light guides can be resiliently flexible or can be mounted such that they can be moved partially outwards to again mount and release the sleeve 17. For example, the light guide may be tilted, bent or translated to this end.

As can be seen in fig. 12A, a spring 117 may be provided below the sleeve, which may be loaded by placing the sleeve and/or by moving the piston 109 and the rod 111 forward, so that at least when the piston 109 is near or in the end position, the reservoir is substantially empty, and the capsule 17 is released by the coupling means, such as a light guide, the capsule is pushed at least partly out of the housing by the spring 117, so that it may be easily removed, e.g. by tilting the apparatus 1 over a trash can or the like, so that a user does not have to contact or only minimally contacts the used capsule.

Fig. 12 shows a portion of the housing or shell 15 before dispensing, with applicator units 104, the applicator units 104 carrying the capsule 17 with the closure cap 37. In the present embodiment, the cell 104 is shown as having a sleeve similar to that in fig. 12A, and such a cell 104 is shown in more detail in fig. 13. In this embodiment, the push rod 111 includes a hollow cylinder 120 that engages the piston 109 and a rod portion 121 mounted on a spindle 122 of a motor 123. A spring 124 is provided in the cylinder 120, the spring 124 biasing the rod portion 121 away from the cylinder 120. The rod portion 121 is provided with two wing portions 125, which wing portions 125 extend laterally and slide along a sliding surface 126 in the housing 15, so as to prevent the rod portion 121 from rotating about the axis 13 and about the spindle 122. The stem portion is provided with internal threads 127 complementary to the threads 128 on the spindle. Thus, rotation of the spindle 122 in a rightward direction, driven by the motor 123, will cause the rod portion, and thus the push rod 111, to move axially, thereby pushing the piston 109 into the reservoir 102. The spring 124 is resilient so that the piston 109 can be pushed against the wall 21, substantially completely emptying the reservoir. However, when the piston 109 has moved to the end position, the rod portion 121 can move slightly further to load the spring 124 such that it is pushed out by the spring 124 when the capsule 17 is released.

When the capsule 17 is again positioned, the switch may be operated to enable the apparatus, in particular the light source 9 and/or the motor 123.

The general concept of the device 1 of fig. 12 is also used in the embodiments shown in fig. 13-15, but with a different structure.

Fig. 13A shows a cross-sectional perspective view of the apparatus 1, wherein the enclosure 17 is as described with reference to fig. 12. However, in the present embodiment, the coupling means between the enclosure 17 and the housing 15 are arranged differently. In this embodiment, the housing 15, or at least the unit 104, comprises a pivotally mounted arm 129. The arm 129 has a hook 130, which hook 130 can be fitted in the groove 103 of the enclosure 17, in particular in the vicinity of the transition between the wall 106 and the housing part 110A. The spring 131 biases the arm so that the hook 130 is pressed into the recess 103. The opposite end 132 of the arm 129 may be pushed so that the hook 130 is pivoted out of the groove 103. The capsule 17 can then be released from the housing 15 and pushed out by the spring 124 as previously discussed.

In fig. 13A, the cover 37 is mounted on the capsule 17, on the ball 7, wherein the cover 37 comprises an edge 38A on the side facing the ball 1, the edge 38A pressing the ball 7 against the opening 108, in particular against a sealing ring 108 surrounding the opening 108. Thus, when the cap 37 is mounted, the ball 7 closes the opening 108.

In the embodiment of fig. 13 (which includes all of fig. 13A-13H), the piston 109 has a face facing the opening 108 that is adapted to snugly fit against the wall 21 to minimize the remaining volume of the reservoir 102 as the piston 109 moves forward against the wall 21.

Fig. 13B-13I show the sequence of placing the capsule 17, dispensing the product 3 and removing the capsule 17 again. In fig. 13B-13I, only the cell 104 and capsule 17 are shown.

Fig. 13B shows the lever portion 121 in the rear end position (i.e. closest to the motor 123) and the enclosure 17 with the cover 37, the enclosure 17 being held close to the insertion opening 15A of the housing 15 or at least of the unit 114. The piston 109 is also in the rearmost position, with the volume of the reservoir 102 being at a maximum. Fig. 13C shows the capsule during insertion into opening 15A, hook 130 sliding along wall 106, biased against wall 106 by spring 131. In fig. 13D, the capsule 17 has been inserted to the maximum extent so that the hook 130 can engage the groove 103 to lock the capsule 17 in place. The rod 111 engages the piston 109, in particular the recess 112 therein. The cover 37 may then be removed, as shown in fig. 13E. The device 1 is then ready for use.

By driving the motor 123 the piston is moved forward to dispense product 3 from the reservoir 102.

Fig. 13F shows the unit 104 with the capsule 17, the piston 109 maximally moved forward by the motor and the reservoir emptied. Then in fig. 13G, the motor 123 has been driven slightly further, so that the spindle 122 has moved the rod part further forward, loading the spring 124. Then in fig. 13H the arm is shown pivoted so that the hook 130 is pulled out of the groove 103, thereby releasing the capsule 17. Thereby, the capsule 17 is pushed out of the housing 15 by the spring 124, as shown in fig. 13I.

In fig. 13, light is guided through a light guide 113 beside the reservoir 102 to the envelope 17 and radiated out through the ball 7.

Fig. 14A shows a cross-sectional perspective view of an alternative embodiment of the cell 104 and enclosure 17, wherein the enclosure is also substantially as shown and discussed in fig. 12 and 13. One difference is the recess 103A in the outwardly facing side of the wall 106. In the present embodiment, as in fig. 12 and 13, the unit 104 has a generally cylindrical housing portion 104A, the housing portion 104A having a first end 104B forming the insertion opening 15A. In the present embodiment, the push rod 111 is generally solid, having a bore containing internal threads 127 for mating with threads 128 on the spindle 122. In the housing 104A, close to the first end 104B, a guiding element 133 is provided for receiving the capsule 17 or at least the reservoir 102 thereof. The guide element 133 may, for example, be generally cylindrical and have an annular cross-wall 134 with an opening 135 through which the push rod 111 can extend to engage the piston 109. A further cross wall 136 is provided spaced further from the end 104B in the unit 104, the push rod 111 also extending through the cross wall 136. A spring 137 is provided between the two

cross walls

134 and 136 and surrounds the push rod 111. In the wall 138 of the guide element 133A plurality of openings 171 are provided, each containing a ball element 139, which ball elements 139 in the coupled position shown in fig. 14A extend into the recess 103A, locking the capsule in the guide element 133, since in this position the balls 139 cannot move outwards due to the wall of the cell 104.

As can be seen in fig. 14A, the wall 138 comprises a further opening 140, for example on the side of the cross wall 134 opposite the ball element 139, in which opening 140 the hook 130 of the arm 129 can be engaged when the guide element 133 has been pushed maximally into the housing 104. The arm 129 is pivotably mounted in a wall of the unit 104, biased by a spring 141 to force the hook 130 into the opening 140 to lock the guide element 133 in place. In this position, the spring 137 is loaded, biasing the guide element 133 and thus the capsule 17 in the axial direction out of the

housing

15, 104.

In the inwardly facing side of the wall of the housing 104A, a groove 143 is provided, so that if the guiding unit 133 is moved outwardly, the ball 39 can be moved outwardly into the groove 143 to release the capsule 17 from the guiding element 133. Thereby, the capsule can be removed again.

In fig. 14 (including all fig. 14A-14I), the light source 9, such as the LED 9A, may for example be provided in a cross wall 136, with at least one light guide 113 being provided by or in the guiding element 133. A switch 144 may be provided in the unit 104 so that the guide element 133 can operate the switch when pushed into the housing 15. This switch 144 is thus capable of switching the electrical circuitry, e.g. the motor and/or the light source, so that the device, or at least the light source 9, cannot be actuated if the capsule is not properly positioned.

Fig. 14B shows the unit 104 with the capsule 17 separated from the unit 104. As in the embodiment of fig. 13, a cap 37 is placed over the ball 7, pushing the ball against the edge 108A to close the opening 108. In the housing 104A, the guide element 133 is moved outwards towards the end 104B, so that the ball 139 is received in the groove 143, so that the capsule 17 can be pushed into the guide element 133. The lever 111 is in the rearward position and the spring 137 is relatively relaxed.

In fig. 14C, the reservoir of the capsule 17 is received in the guide element 133 so that its end abuts the cross wall 134. In fig. 14D, the capsule 17 and the guide element 133 are shown pushed further along the axis 13. Since the groove 143 has an inclined surface, the balls 139 will with the guide element 133 and be forced inwards into the groove 103A in the capsule 17, thereby locking the capsule in the guide element 133. As shown in fig. 14D, the arms 129 are pushed outward so that the guide elements 133 can be transferred to the position shown in fig. 14E, in which the hooks 130 are pushed back into the openings 140 to lock the guide elements 133 in this position. The spring 137 has been compressed and is thus loaded. The switch 144 has been operated so that the device can be used. The push rod 111 engages the piston 109.

In fig. 14F, the push rod 111 and piston 109 are shown in a position maximally moved forward by the motor 123 and spindle 122 so that the piston 109 engages the wall 21. The reservoir has thus been emptied and product 3 is dispensed from the reservoir. If in this position the arm 129 is engaged so that the hook 130 is pulled out of the opening 140, as shown in fig. 14G, the spring 137 pushes the guide element 133 back out to the end 104B so that the ball 139 can move back into the recess 143, as shown in fig. 14H. From this position, the capsule 17 can be taken out of the guide element 133 and thus from the housing 15, see fig. 14I.

Fig. 15A shows an embodiment wherein the capsule 17 comprises an annular reservoir 102 with an annular piston 109. In this embodiment, the push rod 111 is in turn carried by and movable by a motor 123 having a spindle 122, and has a generally cylindrical end 111A adapted to engage the piston 109. A light source 109, schematically shown as a rectangle, is provided centrally near the insertion opening 15a of the unit 114, and the light source 109 can in turn contain one or more light elements, such as but not limited to LEDs, which in use can emit light through the wall 21 and the ball 7. In this embodiment, one or more openings 108 may be provided for connecting the reservoir 102 with the space 11B surrounding a portion of the ball 7.

Fig. 15B illustrates an embodiment in which the light source 9 and the reservoir 102 are positioned in a side-by-side relationship when the enclosure is coupled to the unit 114 and/or the housing 15. In the present embodiment, the drive mechanism including the motor 123 and the push rod 111 has been shown with the spring 124 between the rod portion 121 and the front end portion 120, as generally shown in fig. 13. However, other configurations are also contemplated, including but not limited to those shown in fig. 12 and 14. In the present embodiment, the opening 108 is shown to be lateral to the central axis 13, but it may also be positioned on the axis 13. The coupling between the enclosure 17 and the unit 114 or the housing 15 can be achieved in any suitable manner, such as the manner described previously. Unlike the previous embodiment, where the sleeve may be rotationally symmetric, only one position may be selected for insertion due to the asymmetric form, at least as far as the coupling is concerned.

Fig. 15C shows an embodiment of the unit 114 that is substantially similar to the unit of fig. 13, however in which the arm 129 is positioned and designed differently so that the lever portion 121 can engage the end of the arm opposite the hook 130 so that when the piston 109 has moved forward so that the reservoir 102 has been emptied, the lever portion 121 contacts the arm 129 and as the lever portion 121 moves further towards the enclosure 17, the spring 124 is loaded as described previously and the arm 1209 is pivoted by the lever portion 121 to release the hook 130 from the recess 103. Thereby, the capsule 17 is automatically released from the unit 114 and the apparatus 1.

Fig. 16A and 16B disclose an embodiment of the present disclosure that also provides a sleeve 17 and a housing 15. The present embodiment will be described mainly with respect to differences from the previous embodiments. The same or similar components are denoted by the same or similar reference numerals as used in fig. 1 to 15. In this embodiment, the sleeve 17 is partially inserted into the end of the housing 15 and may be releasably connected thereto in any suitable manner, as discussed for example in the previous embodiments. In this embodiment, a light source 9, such as an LED, is provided inside the housing 15, which may radiate light through a portion of the envelope 17 towards the skin surface (not shown). In fig. 16B, the light rays 90 are schematically shown, which partially pass along the sides of the applicator elements 7 (here shown as balls 7 as discussed previously). In this embodiment, at least a part of the light is irradiated on an area surrounding the application area 30 between the movable element 7 and the surface 5, such as the skin. If the applicator element 7 is made transparent to said light, a portion of the light may also pass through the applicator element 7. If different light frequencies are used, the applicator element may be made of a plastic material that is transparent to one or more of these frequencies and opaque to the other frequency or frequencies. Thus, a portion of the light may pass through the ball, while another portion of the light may only pass along the sides of the ball. Similarly, the sleeve may be at least partially made of a material that is transparent to only a portion of the light used, so that another portion cannot pass through that portion of the sleeve and can only leave the applicator, for example, by the applicator elements (such as by the balls 7).

In this embodiment, as in the previous embodiments, the

light

9, 9A may be positioned directly near the end of the sleeve 17, or may be positioned further inwards in the housing 15, wherein one or more light guides 113 may be provided for conveying the light from the

light source

9, 9A to the sleeve 17.

The cartridge of the present disclosure may be provided with one or more light guides 113 for conveying light from the

light source

9, 9A in the housing and/or the light guides 113 to specific areas of the cartridge 17 for exiting the light to the skin and/or to the applicator elements 7.

Fig. 17 discloses an embodiment of the present disclosure that also provides a sleeve 17 and a housing 15. The present embodiment will be described mainly with respect to differences from the previous embodiments. The same or similar components are denoted by the same or similar reference numerals as used in fig. 1-15. In this embodiment, the sleeve 17 is partially inserted into the end of the housing 15 and may be releasably connected thereto in any suitable manner, as discussed for example in the previous embodiments. In this embodiment, the

light source

9, 9A may still be provided in the housing 15 or on the housing 15. In this embodiment, the applicator element 7 is provided as an immovable element provided at the outwardly facing end of the sleeve 17. The applicator element 7 is shown as a generally smooth, curved element having a convex outer surface 30 forming a dispensing area. In this embodiment, the light guide 113 is shown extending along the side of the reservoir 102, and the exit end 116 of the light is close to the applicator elements 7, preferably such that these ends 116 are shielded by the elements 7. An opening 108 (here shown as a channel) connects the reservoir with the dispensing region 30 of the applicator element 7. During use, the reservoir 102 is emptied by forward movement of the piston 109, thereby reducing the volume to preferably about zero milliliters. The product 3 will be forced out of the opening 108 and will be dispensed on the surface 30 and on the skin by the movement of the element 7 over the skin.

In a preferred embodiment, at least a portion of the emitted light passes through at least a portion of the sleeve 17. This may have the advantage that the sleeve may be used to influence the emitted light, e.g. direction, scattering, color, frequency, intensity and power, etc. This may for example provide the possibility to use the same light source 9, in particular the same LEDs 9A, for different products to be dispensed, wherein the light frequency and/or the intensity of the light and/or the position of the light contacting the skin may be influenced depending on the product to be dispensed and the desired interaction. The sleeve may in fact be used as a filter for the light.

Since in the preferred embodiment of the present disclosure the applicator element will be substantially impermeable to the product 3 and will not absorb said product, it is easy to ensure that the limited amount of product dispensed is indeed all precisely dispensed on the skin. This provides a highly accurate system with little to no loss of active product 3 because the drive means accurately dispenses the limited amount of product. Since, in a preferred example of the present disclosure, the applicator element 7 will not substantially deform during application of the product onto the skin, it will press against the skin such that it will provide a contact area that elastically deforms the skin around a portion of the surface and may provide a more preferred skin massaging effect than when using a soft element such as a sponge.

In a preferred embodiment of the present disclosure, preferably, the only contact between the device and the skin to which the product is to be dispensed is provided by the applicator element 7, the applicator element 7 being part of the disposable cartridge 17. For example, the

light source

9, 9A is shielded from such contact by at least a portion of the sleeve. Thus, hygiene is improved and the device does not have to be cleaned as often as e.g. some of the prior art devices.

In embodiments of the present disclosure, preferably, the sleeve is releasable from the device without the user having to touch the sleeve, which further improves hygiene. In embodiments of the present disclosure, preferably, a mechanical drive is used to reduce the volume of the reservoir 102 and dispense the product 3. This improves the accuracy of the movement and volume reduction compared to other drive means, such as magnetic, whereas the mechanical drive is economical and reliable and prevents electromagnetic fields that are detrimental to the user.

The device 1 according to the present disclosure may comprise a control unit 146, the control unit 146 preferably being connected to the motor 123, the light source 9 and/or the switch operated by the positioning of the capsule 17 as described. Preferably, the control unit may control at least the drive formed by or comprising the motor 123 to reduce the volume of the reservoir 102 to substantially zero millilitres, during a single dispensing cycle of less than 15 minutes, in particular less than 5 minutes. The control may be set to cause the actuator to reduce the volume of the reservoir 102 in one continuous step or intermittently including a series of dispensing steps each of a few seconds. The control unit may for example be programmed to operate the motor 123 so that the piston 109 is driven forward into the reservoir in order to dispense the product. The motor 123 may, for example, be driven so that the piston is driven forward intermittently, stepwise, so that the product is dispensed in a plurality of quantities, for example equal portions, in a plurality of steps each having a predetermined duration. For example, the controller may be set to dispense 1/n of the volume of product 3 from the reservoir every X seconds, so that in n X second steps the entire product is dispensed, while in each cycle the ball 7 can be rolled over the surface 5 for spreading the product over a different part of said surface. For example, n may be between 1 and 50, for example between 4 and 20, such as, for example, between 8 and 15. In the test example, n is chosen to be 12, and the duration X of each period is chosen to be 15 seconds. Thus, all of the products 3 are dispensed in 12 cycles of 15 seconds each. However, the duration of the cycle and/or the number of steps may be selected as desired. In an embodiment, the control unit 145 may be provided to select between different dispensing regimes or to set the number of steps and/or their duration by the user.

A single dispensing cycle is to be understood as a relatively short period of time during which the user dispenses an amount of product onto the relevant portion of his or her skin for a single treatment of that portion of skin. For example, for each such portion, a different sleeve may be used for the same portion of skin for subsequent treatments, such as daily treatments, and a separate sleeve may be used.

The present invention is in no way limited to the specific embodiments disclosed and described herein. Many variations are possible within the inventive concept. For example, the light source 9 may be provided at least partially in the sleeve 17, so that a specific light source may be provided for each sleeve, for example, depending on the product to be dispensed. Instead of a piston, it is possible to have a membrane as the movable wall. A plurality of openings may be provided to enable the product to be pushed onto the applicator elements. The sleeve may be connected to the housing 15 differently, for example such that it can be slid into the housing from one side, i.e. in a direction perpendicular to the longitudinal axis of the housing. Instead of a motor, other means may be provided for reducing the volume of the reservoir, such as compressed gas, a manually operated pressure applying device, a spring, etc.

These and similar modifications are to be considered as having been disclosed herein.
